... they want their meme back.
We hear the same tiring rant over and over again, and this is really becoming OLD. Plain and simple, in that case, this is bollocks. I've run every version of KDE since v. 1, and anytime there was improvements, whiners have complained they were too broke to afford the required computing power. Then, don't use it and be done with it !
But what's more, since KDE 4.5, this rant is completely delusional. I use daily a 2008 eeepc 900A (Atom powered low-end netbook w/ 1GB RAM and Intel graphics), with Fedora 13, KDE 4.5 (composite display enabled with bells and whistles), and libreoffice. This is my bread-and-butter computer. The speed of KDE is already perfectly adequate even if slowed down by the lousy 8GB SSD of the machine. All the graphics effects just work. And this from a computer that wouldn't be able to run Microsoft Aero effects.
You don't like KDE : fine. But stop smearing it for imaginary defects produced only by your incapacity to configure it properly.
